Janet bindings to Raylib

jaylib

Janet bindings to Raylib. The bindings are faithful to the original C API, especially where it makes sense, but function names have been "lispified" (kebab case, question marks instead of the word "Is", etc.). See api.txt for an overview of which API functions have been ported.

Example

(use jaylib)

(init-window 100 100 "Test Game")
(set-target-fps 60)
(hide-cursor)

(while (not (window-should-close))
  (begin-drawing)

  (clear-background [0 0 0])
  (let [[x y] (get-mouse-position)]
    (draw-circle-gradient x y 31.4 :lime :red)
    (draw-poly [500 200] 5 40 0 :magenta)
    (draw-line-bezier
      [(- x 100) y]
      [(+ x 100) (+ y 50)]
      4 :pink)
    (draw-line-ex
      [x (- y 10)]
      [x (+ y 10)]
      4 :sky-blue)
    (draw-line-strip
      [[x 0] [x 100] [50 y] [10 180]]
      :ray-white))

  (end-drawing))

(close-window)

Building

Make sure you have raylib installed on your system. I built raylib from source with the following commands and CMake configuration:

git clone https://github.com/raysan5/raylib.git raylib
cd raylib
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/ -DWITH_PIC=ON ..
make -j 16
sudo make install

Once raylib is built and installed, build jaylib with

jpm build

This should compile build\jaylib.so, which you can import in a janet repl. Tested so far only on linux with Wayland, you will likely need to figure out a working configuration for raylib, as well as some system specific changes in project.janet for your system.

(use ./build/jaylib)

Install

As with building from source, you will need raylib on your system.

[sudo] jpm install https://github.com/janet-lang/jaylib.git
